E-108 Endovascular treatment of patients with acute ischemic stroke due to underlying arterial dissection: a nationwide analysis
ConclusionsDespite a similar prevalence among patients admitted for AIS, CA dissections are associated with a higher rate of endovascular intervention and poorer short-term outcomes compared to VA dissections. This study provides essential epidemiologic and outcome data for the cerebrovascular neurosurgeon.Abstract E-108 Table 1Comparison of clinical characteristics and outcomes among patients presenting with acute ischemic stroke due to carotid or vertebral artery dissections Characteristic Vertebral Artery Dissection, N = 2,562 Carotid Artery Dissection, N = 2,789 p-value1 Age (years), Mean (SD) 53 (17) 57 (17) <0.00...

E-055 Internal carotid artery reconstruction with flow diverting stents in the treatment of acute ischemic stroke: technical considerations and medical management
ConclusionsFDS appear to be a safe and effective tool for reconstruction of a symptomatic dissection in tortuous cervical ICAs. Their flexibility allows conformation to complex anatomies and they can be traversed multiple times by aspiration catheters/stentrievers. We found excellent patency at follow up. The unique challenges posed by utilization of high-profile stents in acute stroke require appropriate technical execution and medical management.Disclosures E. Orru: None. F. Bounni: None. M.

E-094 Trends in endovascular treatment of cervical artery dissections: a nationwide analysis
ConclusionsDespite an increase in the overall use of endovascular therapy for the treatment of cervical artery dissection in patients with ischemic stroke or TIA, there was no significant association with early clinical outcomes.

E-190 Trends in admissions for intracranial dissections in the United States
ConclusionThe prevalence of uIADs among hospitalized patients is scarce, and only 2% of craniocervical dissection-related AIS is due to uIAD. Compared to IAs, patients were more likely younger and male, and uIAD more commonly led to acute ischemic stroke and motor deficits. The trend in age remained stable across the four years analyzed, while the proportion of females increased. There was no trend in the proportion of races among uIADs, however.Disclosures W. Wahood: None. G. Lanzino: None. Z. Keser: None.

E-104 Young man with osteogenesis imperfecta presenting with acute stroke from carotid dissection and subsequent contralateral pseudoaneurysm
ConclusionOsteogenesis imperfecta (OI) has been associated with numerous cerebrovascular conditions including carotid cavernous fistulas, cerebral aneurysms, and carotid dissections with attendant risk of stroke. While our patient was able to be successfully treated for his initial carotid dissection in the acute phase, he was at higher risk for stroke, whereas his subsequent carotid dissection was identified pre-symptomatically and treated electively. Judicious evaluation of patients with OI for cervical carotid dissections is warranted for early identification and treatment.Disclosures A. Mbaluka: None. R. Sanchez-Mejia:...

Stroke prevention by endovascular treatment of carotid and vertebral artery dissections
Conclusions Patients with CAD and VAD differ significantly in presentation, indications for treatment, and treatment methods. Endovascular treatment of CAD and VAD has low procedural morbidity and is associated with a low incidence of future stroke.

E-049 Accuracy of non-invasive and invasive imaging in identifying ica occlusion: a comparative study in 65 patients
Conclusion Our result suggests that there is a lack of correlation between the imaging findings of carotid occlusion on imaging compared with catheter angiography of the ICA during the intervention in acute stroke treatment. Thus, endovascular catheterization of the ICA is often required for the exact characterization and localization of the carotid occlusion and to determine if a dissection is the underlying pathology in such cases.

Critical assessment of complications associated with use of the Pipeline Embolization Device
Conclusions Despite a low rate of permanent complications associated with the PED in this series, the total complication rate was high. This finding supports the conclusion that this device should be reserved for the most challenging aneurysms. Patients should be advised of this higher rate of transient periprocedural complications. Trial registration number IRB#:14BN027 Q7.

Endovascular treatment of fusiform intracranial vertebral artery aneurysms using reconstructive techniques

E-007 Unusual Two Cases of Dissecting Cervical Internal Carotid Artery Pseudo-aneurysm with Symptomatic Intracranial Aneurysm
Conclusions In the evaluation of suspected intracranial aneurysm who present with headache with neck pain, a catheter cerebral angiogram not only will clearly define the correct morphology of intracranial aneurysm but also will appropriately identify the presence of life threatening cervical ICA abnormalities. Additionally, presence of an unusual cervical ICA anatomy with DP may warrant further evaluation of intracranial blood vessel of same territory. Using endovascular strategies, both extracranial and intracranial DP could be treated. However, long-term follow-up and outcome is unknown. Further studies are required. Di...
